摘要： An input color signal is converted into a color signal representing a color which is visually closer to a color represented by the input color signal by performing gamut mapping processing based on the visual characteristics of humans. An image processing method includes the steps of inputting color signals, and performing gamut mapping processing in which the input color signal is converted into a color signal having a hue different from the hue of the input color signal based on a locus set corresponding to the hue and color saturation of the input color signal in color space.

The amount of phase shift can be continuously changed by changing these variable capacitance devices continuously. Moreover, these devices can be formed on a semiconductor, thereby realizing low-voltage driving and high-speed response. Furthermore, the variance of impedance can be prevented by adjusting these two variable capacitance devices, whereby transmission efficiency can be improved

摘要： An object of this invention is to improve the operability of color adjustment by using a simple hardware arrangement which performs only a matrix arithmetic operation having matrix coefficients properly determined in accordance with adjustment amounts designated from an operation unit for adjusting three variables as lightness, saturation, and hue. In the constitution of this invention, an image input unit inputs a color input signal, and a color conversion unit extracts the minimum value from the input color signal for each pixel, obtaining a difference signal of the input color signal and the extracted minimum value signal. The obtained difference signal is converted in matrix in accordance with matrix conversion coefficients generated by a matrix conversion coefficient unit in correspondence with the adjustment amounts of the adjustment items of an operation unit for adjusting three variables as lightness, hue, and saturation.

摘要： An image processing apparatus extracts an edge or line portion of an image, judges grayness of the image, and processes the image according to outputs of the means used for the edge- or line-extraction and grayness-determination. The further processing may, for example, comprise undercolor removal and/or black-addition. Edge extraction can be performed by use of a Laplacian. The grayness can be judged by, for example, providing a colorlessness signal formed from two color component signals. Extraction of a line region, instead of Laplacian edge extraction, can be performed, for example, by use of an Hadamard transformation. Also, the invention more generally includes detecting grayness of an image, detecting other characteristics of the image, and judging additional characteristics of the image according to the first two determinations.
